Separate regolith growth panel from processed-culture biofertilization #1585

Mars_Regolith_Cyanobacteria_Biofertilizer_Panel; PMID:35865930. Preserve extract chemistry, separate25-day phototroph OD/FvFm growth and7-day Lemna response to filtered/sonicated cultures. These are not NICHE_PARTITIONING or live COMMENSALISM. Diazotrophy is a proposed explanation, not measured N2 flux; phosphorus not detected in extract and inoculum/reserves matter. Remove growth-advantage-to-biofertilization arrow: worst-growing Arthrospira/Chlorella cultures give stronger Lemna dry-weight outcomes than Nostoc. Preserve positive Arthrospira filtered/sonicated and Chlorella filtered dry weight, distinguish lower frond yields, absence of significant filtered/sonicated differences and unisolated nutrient mechanisms. Coordinate modeling with #573, not a duplicate panel-schema task. Close repair only after protected-main merge.
